Intrusion detection provides a way to identify and thus allow responses to, attacks against these systems. Detecting an attack as it occurs is one thing, stopping it is another. The highest priority of any IT security activity in this area is to prevent an attack and possible related disaster; IDS often deliver little to meet this demand. So, the Intrusion Detection System (IDS) was extended and then comes Intrusion Prevention System (IPS). The inadequacies inherent in current Defenses have driven the development of a new breed of security products known as Intrusion Prevention Systems (IPS).
